Patented Dec. 22, 1931 UNITED STATES PATENT OFFICE GEORGE BAXENDINE cooxnn, or easronm, NOR-TH CAROLINA, ASSIGNOR ro COOKER MACHINE AND FOUNDRY COMPANY, OF GASTONIA, NORTH CAROLINA, A CO RPORA- TION OF NORTH CAROLINA WINDING MACHINE Application filed April 19,

This invention relates to winding machines variously used for example in the textile industry to wind yarns into the form of cylindric or conical packages known as cheeses or cones to wind yarns on spools, etc., and has more particular reference to that type of winding machines wherein a multiplicity of winding units are serially arranged in rows along opposite sides of the machines so as to be conveniently accessible to the attendants. The care of such a machine is very tiring due to the distance which must be repeatedly traversed by the attendant in the performance of the required duties.

The main object of my invention is to minimize fatigue incident to operation of a winding machine of the kind referred to through provisions whereby the attendant is continuously conveyed around the machine so as to pass the winding units at a rate of progression such that ample time is afforded to replace empty bobbins, to join yarn ends, etc.

In means appropriate to the attainment of the above ends I moreover aim to provide for automatic speeding up of travel around the ends of the machine between the straight or active portions of the circuit toprevent unnecessary loss of time; as well asto provide for stoppage at any point in the circuits at the will of the attendant.

Still other objects and advantages will be manifest from the detailed description following when taken in connection with the attached drawings, whereof Fig. I is a view in side elevation showing my invention in association with a standard or commercial type of winding machine.

1929. Serial No. 856,503.

The winding machine chosenforthe purpose of illustration herein is of the kind embodying a multiplicity of winding units which are serially arranged in rows along opposite sides of the machine frame, each of such winding units consisting of a bobbin spindle S suitably supported near the bottom of the machine frame in vertical alignment beneath driving means by which the yarn package or cone C is revolved concurrently with passage of the yarn thereto under control of horizontally reciprocating or traversing guides G.

In adapting my invention to a winding machine of the sort above briefly described, I provide an endless railway 10 with straight portions 100 along the sides of the machine, and curved connecting portions 10?), around the ends of the machine. As shown, the railway 10 serves as a track for a wheeled carriage 11 whereon is mounted a seat 12 for the attendant or operative, said carriage being progressed on the track by virtue of connection, through acoupling means 13 (Fig. V), with an endless propelling cable or sprocket chain 14 which is trained about horizontally disposed guide wheels 15, 16 (Figs. I and II) that revolve on positionally fixed axes 17 18 concentric with the curved end portions 10?) of the track 10. The drive means for the propelling cable or chain 14 includes, in the present instance, an electric motor 20 (Figs. IV and V) with a two speed transmission 21 whereof the shaft 22 is fitted with a worm 23 in mesh with a gear 24. A drive pinion 25 on the shaft 25 supporting the gear 24 engages an endless sprocket chain 26 which in turn drives sprocket wheels 27, 28 (Figs. I and II) fixed on the axes -17, 18 of the guide wheels 15, 16 of the propelling cable or chain 14. A pair of idlers 29 (Fig. V) cooperate with the driving pinion 25 to insure more positive engagement between the latter and the chain 26. Referring still more particularly to Figs. IV and V, the shaft 22 of the transmission carries two loosely mounted high and low speed spur wheels 30, 31 that mesh respectively with gear pinions 32, 33 fast on the shaft of the motor 20. To enable selectivity between the gears 30,31, use is made of a clutch means comprising a pair of friction disks 84, 35 which are secured to a sleeve 36, having a splined connection with the transmission shaft 22 so as to be shiftable endwise in the interval between said gears by a fork lever 37 fixed to a transverse rock shaft 38. The parts ust described are normally maintained in the position illustrated, i. e. with the clutch disk 35in contact'with the gear 31, through the influence Ora counterweight on an arm 39 secured to the rock shaft 38. Shifting of the clutch in the reverse direction to bring the disk 34 into engagement with the low speed gear wheel 30 is effected, in opposition to the counterweighted lever 39 by means of lugs 40 projecting upward from the carriage chain or cable 14 at intervals, said lugs being adapted to engage the free end of a .cen-

trally pivoted tappet lever 41, which, through a link 42, is coordinated with athird arm 43 fixed to the rock shaft 38. Upon being shifted to the position shown in dotted lines 111 Fig. V by the chain lugs 40, the lever 41 is temporarily locked by a latch 45 wlth a hook projection 45a (Fig. IV) at one of its extremities. This latch 45 is pivoted to a fixed floor bracket 46 and has a tail 45?) which under-reaches the sprocket chain 26, said tail terminating in a cam slope 450 (Fig. IV)

that lies inthe path of lateral lugs or proj ections 47 of the propelling cable orchain 14. When engagedby these pro ections 47 the latch 45 is obviously tripped so as to release the tappet lever 41 and permit restoration of the clutch means to the normal illustrated position under the influence of the counterweighted lever 39; which, it will be readlly, understood never rocks upwardly to or beyond the vertical when influenced by said tappet lever. 7 i

' In the operation of my invention, the carriage 11 is moved along the straight sections 10a of the .track at opposite sides of the machine underslowspeed drive of the propelling cable or chain 14, thespeed being proportioned in actual practice to the package winding period such that the operative is afforded ample time to replace empty bobbins, to remove the completed packages, etc., incident to transit. At about the time the carriage 11 haspassed the last winding disk 34 concurrently brought into contact with the high speed gear 30, to the end that the speed of the cable or chain 14 is increased. The carriage 11 is accordingly progressed about the left hand end of the machine at a faster rate with avoidance of loss of time, the speed being of course predetermined so as to be consistent with safety for the operative. Just as the opposite straight portion 10a of the track 10, along the bottom of Fig. II, is reached, one of the lateral lug proj ections 47 on the propelling chain 14 engages the inclined cam 45c of the latch 45, thereby tripping the latteri and releasing the tappet lever 41 to permitrestoration of .the clutch to the normal or full line position by the gweighted'lever 39, likewise as already understood. This is followed by slower progression of the carriage 11 along the straight portion 10a of the lower track 10; and, when this has been traversed, the operation is repeated at the right hand end of the machine to bring said carriage around again at high speed to the upper portion ofthe run through cooperation of chain lugs 40, 47, respectively with thetrip lever 41 and the latch 45 in precisely the same manner as previously described.

The carriage 11 may be stopped at any point along the straight portions 10a of the track circuit through depression by the operator of a pedal 50. As shown, this pedal 50 is pivoted to a fulcrum bracket 51 on the carriage .11, and overtravels clutch release :bars 52 along opposite sidesofthe machines. sald bars belng sustained near the ends of the machine by arms 53, 54 afiixed to auxil- 1ary rock shafts 55, 56, as well as by arms 57 secured to the ends of the rock shaft 38 previously described. Like the rock shaft 38,

the auxiliary rock shafts 55, 56 are respectively provided with weighted arms 58, 59

to resist the depression of the bars 52 by the clutch release pedal 50 on the carriage 11. When the pedal 50 is depressed so as to engage either, of the release bars 52, the imparted movement results in depression of the release bar 52 into contact with the platform of the carriage 11 as readily understood from Fig. III, which moves the clutch disks 34, 35 to aneutral position free of both the gears 30, 31 so that-said .carriage is brought to rest at the desired point, thereby enabling the operative-to attend to any emergencies likely to arise incident to passing the winding units at opposite sides of the machine.

While I have herein shown and described my invention in connection with yarn winding machines, I do not wish to be limited" to this particular field alone since it may obviously be used with attainment of corresponding advantage in connection with other machines forwinding or spooling materials in strand form even including wire.
